Outdoor Ecosystem Lab Activity for High School Biology Students

Spring is the perfect time for an outdoor ecosystem lab, but a successful outdoor science activity requires clear structure, strong expectations, and a meaningful assignment.

If you are looking for an outdoor ecosystem lab for high school biology, spring is one of the best times of year to do it. Students are ready to get outside, ecosystems are active and changing, and it is much easier for students to observe real relationships between organisms when they can see them in context. This outdoor ecosystem lab activity is designed specifically for high school biology students studying ecosystems, food webs, and ecological interactions.

This outdoor ecosystem lab activity is designed specifically for high school biology students studying ecosystems, food webs, and ecological interactions.

One challenge with outdoor learning is that it can easily turn into unstructured time if students are not given a clear purpose. That is why I like using a detailed ecosystem field study instead of simply sending students outside to observe nature. When students have a specific area to study, a clear set of directions, and focused analysis questions, outdoor time becomes meaningful science learning.

My Exploring an Ecosystem activity gives students a structured way to examine a small outdoor ecosystem, map what they find, and analyze the interactions between living and nonliving factors.

What Students Do in This Outdoor Ecosystem Lab

In this activity, students work in small groups to study a 5 m x 5 m outdoor ecosystem. They mark off the area, map the physical features, identify living organisms, and record evidence of ecological interactions. Students then use their observations to answer detailed analysis questions and create food chains and food webs.

This lab goes far beyond a simple nature walk. Students are expected to observe carefully, think critically, and support their ideas with evidence from the ecosystem they study.

During the activity, students:

• map the physical features of an outdoor study site
• identify biotic and abiotic factors
• look for evidence of predator-prey relationships, competition, camouflage, and symbiosis
• identify producers, consumers, decomposers, autotrophs, and heterotrophs
• construct food chains and food webs based on what they observe
• analyze how the ecosystem may change over time

Because the assignment is detailed and structured, students are much more likely to notice the interactions happening around them instead of treating outdoor time like a break from learning. If you want a structured, ready-to-use version of this activity that saves you time, I’ve put everything together for you.

Ecology Concepts Covered

This outdoor science activity works especially well during an ecology unit because it reinforces so many important concepts in a real setting.

If you are looking for additional ways to reinforce these ideas, you may also like reading this blog post on food chains and food webs activity or this one on  population ecology lab.

• ecosystems
• biotic and abiotic factors
• autotrophs and heterotrophs
• herbivores, carnivores, omnivores, detritivores, and decomposers
• predator-prey relationships
• symbiosis
• food chains and food webs
• trophic levels
• limiting factors
• human impact on ecosystems

Pros and Cons of Outdoor Science Activities

Pros of outdoor science activities:

• Students are highly engaged when they are working outside.
• Ecology concepts become more concrete when students can observe real examples.
• Students practice careful observation and real-world data collection.
• Students begin to notice patterns and relationships they would normally overlook.
• Outdoor labs support visual learners through mapping, drawing, and labeling.
• Students develop stronger awareness of their surroundings.
• Group work feels more natural and collaborative outdoors.
• These activities often create memorable learning experiences.
• Students build appreciation for nature and environmental responsibility.
• An ecosystem can be studied almost anywhere.

Cons of outdoor science activities:

• They can be time consuming.
• Classroom management requires planning and clear expectations.
• Students may treat outdoor time as free time if structure is weak.
• Weather can impact the activity.
• Some environments limit what can be observed.
• Students may need more guidance with open-ended observation.

What This Looks Like in Your Classroom

This project is easy to set up and requires simple materials.

• an outdoor ecosystem
• poster board or white paper
• colored markers
• 4 stakes
• string
• meter stick
• magnifying glass or hand lens

Charles Darwin: The Tale of Evolution

Over 130 years have passed since the death of Charles Darwin.  Despite the passage of time since Darwin first presented his ideas on natural selection, there continues to be controversy surrounding his theory of evolution.  In 1973, Theodosius Dobzhansky published an essay in American Biology Teacher in which he stated, “Nothing in biology makes sense except in the light of evolution.”  Truer words were never spoken.  When teaching a biology class, we shouldn’t limit our students to a single unit on the theory of evolution.  Rather, the theme of evolution should be woven throughout every unit we teach.

I designed this teaching resource to teach my biology students about the man, Charles Darwin.  Darwin was a religious and thoughtful man, as well as a superb scientist.  However, I have found that I still have students in my class who view him in a less than complimentary light.  My main goal in writing this journaling activity was to provide my students with the facts and information they need to form their own opinions and conclusions based on the evidence presented.  After all, that is the goal of science, right?

Before diving into natural selection, many teachers find it helpful to introduce students to the geologic time scale and the history of life on Earth. You can see in this blog post how I teach this using a geologic time scale worksheet and activity.

I had two goals in mind when writing “Darwin’s Diary.”  First, I wanted to include enough biographical information about Darwin to teach my science students about his life.  Second, I wanted to produce a class project that would require my students to be thoughtful and introspective, while at the same time, ensure that they master the concepts of evolution.

What will the students be doing?

This teaching resource is written as if it were a diary kept by Charles Darwin throughout his life.  The entries in the diary are designed to teach about the life of Darwin, and the events that led him to develop his theory of evolution.  The 26 diary entries include facts and information about Darwin as well as actual quotes from Darwin.  Students are asked to respond in some way to each diary entry.  In some diary entries students will be asked to offer opinions, but in others, they must provide correct answers to questions.  In order to complete this project, students need to receive instruction in the concepts covered in an “Introduction to Evolution” chapter of a typical high school biology textbook.

I had such a great time doing the research for this evolution journaling activity! Darwin's life was full of the same drama, struggles, accomplishments, and tragedies that we all face today.  Darwin was witty, introspective, and very adventuresome!  I was able to find and use his own writings to use in the diary entries, and his descriptions of his daily life are simply amazing.  In one dairy entry Darwin describes collecting beetles.  Both of his hands were full holding beetles, so in order to catch a new beetle, he popped one into this mouth to free up a hand to catch another!  He describes his struggles trying to please his father, his tiny quarters aboard the Beagle, riding on the backs of Galapagos turtles, marriage, and his concern about the uproar that would be caused by publishing his theory.  As you can see, I am completely captivated by the details of his life, and your students will be as well!

What is needed to complete this assignment?

In order to complete these assignments, students will need to use the following resources:

•  Biology textbook

•  Notes taken during class

•  Online Resources

This diary activity is perfectly aligned with my teaching PowerPoint, “Darwin’s Theory of Evolution.” It includes a 96-slide PowerPoint with notes for teacher and students. Click the image to the right to view this product on TeachersPayTeachers.

How can you use this in your classroom?

•    I suggest copying all pages and passing them out to your students on the first day of your evolution unit.  The activity is designed to be used over multiple days as you teach your unit on evolution.  

•    Use only the pages you want.  There are enough student pages included so that you have the flexibility to choose the pages best suited for your needs. 

•    Each day during your unit, have students complete a number of the dairy entries.  These pages make great classroom activities as well as quality homework assignments.  You will find that the content of the diary entries will generate much classroom discussion.

•    The questions used in this assignment are of two types.  Some questions require the students to express their opinion, but most questions require a research-based correct answer.  I accept any and all answers to opinion-based questions as long as the student has given an honest effort to express his/her opinion.  If this assignment is to be graded make sure that students know that they are expected to provide correct answers for the majority of the questions.

      

    At the end of "On the Origin of Species", Darwin writes, “There is grandeur in this view of life … from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.” This teaching resource is a journey through time that allows our science students to learn about the events throughout Darwin's life that led him to write and publish "On the Origin of Species by Means of Natural Selection."

If you are teaching the origin of life, you can also have students explore this concept with a hands-on lab. In this coacervates lab activity for high school biology, students create and observe coacervates, then design their own experiment to test different variables.

  

Wanna Chat? Reasons why my Chat Lab Stations are working!

The Background Story: A few years ago, I wanted to do something different on the first day of school. Most of the teachers at my school, including me, were doing the same thing all daylong ... Going over the course syllabus, passing out textbooks, reading the dreaded classroom rules. After one class period of this, all that the students heard was "Blah, blah, blah...."  It was definitely time for me to do something different. After giving it some thought, "Biology Chat" was born. My goals for the activity were simple:
(1) Get the kids actively engaged in science on the very first day so they don't dread coming to my class the second day, and (2) Help the students make new friends in our very large school. These goals were accomplished! In fact, the activity was so popular with my biology students that I quickly developed Chemistry Chat for my chem classes.

Biology Chat

Chemistry Chat

Physics Chat

What is the purpose of my "Chat" lab activities? My "Chat" activities are rotating lab stations and involve collaborative student groups. At each station, students collaborate to resolve a problem, accomplish a task, or conduct a minor science experiment. The term "chat" is used to encourage students to engage in meaningful conversation and teamwork, hopefully deepening their comprehension and mastery of the subject matter content. Let's face it. High school students have "socializing" on their minds all day long. The term "chat" resonates with them, and it has a “fun” tone.

What are the benefits of my Chat Lab Stations?

1.  Students are up, out of their seats, and moving! It is a rare student that can sit in a desk for eight hours and still be conscious at the end of the day. Chat lab stations allow students to move around the room, giving them a bit of a mental break between each station.

2.  Group work is an important part of what we do in a science class, and it is a skill that will be needed throughout life. Lab station activities teach students how to work together to achieve a goal.

3. Differentiation! We all teach classes that contain students of widely-varying ability levels. It is not necessary for every student to complete every lab station. For students with IEP's, have them complete only the stations that are appropriate for them. By carefully selecting the small groups, you can create groups that are supportive and will provide an educational atmosphere that will benefit all members of the group. It is also a good idea to have a "challenge" lab station for the early finishers. I never want idle hands in my classroom!

4.  All too often we throw so much information at the students that they quickly become overwhelmed by sheer volume. Each chat lab station focuses on a single task or concept. This prevents students from becoming overwhelmed by too much information.

5.  Peer teaching/tutoring is highly effective! A struggling student may likely learn more from a fellow student than they do from the teacher. One student can offer another student explanations in a low pressure setting that feels safe to the struggling student.

6.  The more informal classroom setting allows me more time to interact with my students. I love being able to walk around the room and speak to every student. It allows me to connect with the student, both personally and academically. Secondary students may not show the same affection for their teachers as do elementary students, but they still want to be noticed, complimented, and see a friendly smile from the teacher.

Tips for Implementation!

1. Consider very carefully how the students are arranged into groups. I never (or rarely) allow students to choose their own lab groups. Do I want the students to have a little "chat" or social time during the activity? Yes, but I want to control it. I want my students chatting, but I want them chatting about the topics and concepts that I need to teach and reinforce. Before my students arrive in my class, I have already placed them in groups. Each week I change the composition of the groups. This prevents the students from becoming too comfortable and failing to accomplish the goals of the lesson.

2. Make sure that your lab stations offer a good mix of teaching styles and strategies. You don't want students labeling a diagram at every single station. They will quickly lose interest in the activity. Make sure that each station offers a different sort of task or activity.

3. Make sure that each station is independent of the other stations. The activity works so much better if students can rotate from one station to another in any order. If the stations have to be completed in a certain order, a lab traffic jam will likely result.

4. Monitor the students! Make sure that students are on task ... all period long!

"Words to Live By" from Famous Scientists

These famous scientists teach us about life as well as about science.

#KindnessNation

#WeHoldTheseTruths

We teach about the work of famous scientists all the time in our classes.  If you take one of my classes, then it is a given that you know that Jonas Salk developed a life-saving polio vaccine, that Stephen Hawking changed the way we think about our universe, that Jane Goodall works tirelessly on behalf of her beloved chimpanzees, and that nothing makes sense in a biology class without the work of Charles Darwin.   These people made (and make) tremendous contributions to various fields of study, but they also have a "human" side.  They teach us not only about science, but about human nature, about the value of hard work, about tolerance and acceptance, and about the importance of perseverance, never giving up, and never losing hope.

Click image to download free mini-posters.

With this in mind, I have developed a set of classroom mini-posters highlighting quotes from scientists that offer words of wisdom.  This is a "forever free" product in my TeachersPayTeachers store.  All of the mini-posters print out on 8.5 x 11 sized paper.  They can be quickly laminated and used to make a bulletin board or wall display.  As our students sit in our classes and look about the room, hopefully their eyes will land on one of these posters and provide them with the inspiration to succeed and overcome the hurdles of life.

So, what's up with the hashtags?  I am honored to join a large group of teacher-authors on TpT in this hashtag event to provide lots and lots of free classroom materials for all subjects and grade levels.  The idea is to provide a wealth of free materials that teach and reinforce character, kindness, tolerance, anti-bullying, empathy, inclusion, and equality for all.  Let's face it ... 2016 was a very difficult year for our nation.  Regardless of your beliefs, opinions or convictions, teachers need materials to bring out the best in our students.  This hashtag event will offer "forever free" materials that are not political in nature, but rather offer quality life lessons.

Here is a sample of the mini-posters.

Be sure to search on TpT, Facebook, and Instagram for these hashtags:  #KindnessNation and #WeHoldTheseTruths.

Motivating Science Students

Consider these points when developing a plan to motivate your students.

As we begin this new semester, I have been giving some thought to the concept of “motivation in the classroom.”   We teachers hold widely varying opinions on this subject.  Some teachers believe whole-heartedly that it is their job to do whatever it takes to gets the students excited and motivated about the learning process.  Other teachers feel that motivation comes from within, and that the student should be held responsible for their own motivation.  I think most teachers, including myself, fall somewhere in the middle of this spectrum.

How hard we must work to motivate our students is directly proportional to the classes we teach.  Every student in our school must take a Biology 1 class, and many of them have no interest in doing so.   But the students in my AP Biology course enroll by choice, and the difference is huge!   My Biology 1 students are often less enthusiastic on the front end of the experience.  I may never convince some of my students to love biology and chemistry as I do, but it is my job as a classroom teacher to instill in my students the desire to succeed.  To that end, I have identified four factors intrinsic to the healthy motivation of students in the science classroom.

We cannot expect students to be willing to learn unless we as teachers are energetic in our approach to instruction.  Students will be more engaged if they see us up, moving about the classroom and burning calories.  Science teachers in a laboratory setting have an advantage.  Demonstrating lively behavior in a lab is built in to the demands of helping and watching students.  We must be careful that lecture opportunities do not turn into a chance to rest.  Don’t be the teacher that sits behind the desk the entire class period.  Your desk is a barrier between you and your students.  Moving amongst your students while you teach will draw them in.  It will encourage them to be engaged and participate more fully in the lesson.

It is essential that some element of fun be attached to instruction.  This does not have to be joke telling or game playing.  A bit of eye candy in the form of colorful and engaging photos or interesting video, or the occasional social opportunity (grouping) will go a long way toward helping a student look forward to returning to your class.  Occasionally the material we must teach doesn't rise to the level of thrilling and exhilarating, but since it must be taught, we should try to find a way to make it more interesting to our students.  A competitive game format, a lab station activity, or a lively class discussion can go a long way to eliminating the boredom factor.  It is imperative that we change our approach from time to time to avoid monotony and stagnation.

Praising students will go a long way towards motivating them.  It is, however, important to note the methodology used when praising them.  Elementary students find more incentive in public praise than do high school students.  It is often necessary to praise high school students individually and not in front of the class.  To older kids, the “cool factor” is sometimes affected by how they are praised.  Know your kids.

The final step in motivating students is to show them the relevance in what they are being asked to do.  Sometimes that relevance is personal (college admission, testing for scholarships, simple work ethic) and sometimes it is professional (job centric subject matter).  Occasional reminders as to the importance of these issues will help, especially considering how many important issues are vying for control of the teenage mind.  Students love to ask, “When will I ever need to know this?”  Making clear to students why they need to master a particular concept or skill is highly motivating to them.  Make this information part of the lesson, rather than waiting for the question to be asked.

In the ideal world, all motivation for students would be “self motivation.” Anything we as teachers can do to help students maintain focus will surely pay dividends in their future.
